Webstart with continuous time signals, and sample them to get discrete time signals. Let the sampling frequency be fs, and the sampling period be ts =1/ fs =2π/ωs. Consider a signal x(t) with Laplace transform (6) ∫ ∞ −∞ X(s) = x(t)e−stdt, and let y[k] =x(kts) be the discrete time signal obtained by sampling x(t) . The Z Transform of ... Web31 Mar 2024 · Re Always Stable Properties of ROC A ring or disk in the z-plane centered at the origin. The Fourier Transform of x(n) is converge absolutely iff the ROC includes the unit circle. The ROC cannot include any poles Finite Duration Sequences: The ROC is the entire z-plane except possibly z=0 or z= . Right sided sequences: The ROC extends outward from …
